Application filed January 28, 1909. Serial No; 474,661.

To all whom it may concern:

Be 1t known that I, Bnuxo Haunt-ix, a

citizen of the United States of America, re-

sidin at East Pittsburg, in the county of Alleg may and State of Pennsylvania. have invented certain new and useful Improvements in a Combined Automobile and Motor- Boat, of which-the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a combined automobile and motor boat, and the object of the invention is to provide an automobile with means to travel on land as well as in water, and is therefor advantageous for the transportation of army supplies or for operation in an army.

' I attain the above object by constructing an automobile body in the. formof a non-" leakable boat, and provide the automobile with propellers adapted to be driven when the automobile enters a stream of water. A convenient form of engine is employed for operating the automobile on land or water and a clutch used for controlling the opera tion of the rear axles of the automobile or propellers thereof.

The invention will be hereinafter described in detail and then specifically claimed.

In the drawings, Figure 1 is a side elevationof an antomolnle constructed in accordance with my invention, Fig. 2 is a. longitudinal sectional view of the same, Fig. 3 is a plan of the combined automobile and motor boat, Fig. 4 is a front elevation of the same, Fig. Sis an enlarged sectional view of one of the steering wheels of the automobile.

In the accoi'npanying' drawings 1 designates an oblong metallic vehiclebody, having the forward end thereof conforming to the bow of a vessel, as at 2, and the rearcnd thereof shaped to conform to the stern of a vessel, as at D f Arranged in t a vertical shaft 4: connecting transverse beams and 6, the former being arranged above the bow and the latter beneath the how. The ends of the beams 5 and 6 protrude beyond the sides of the body and in -the ends of said beams are journaled vertical-posts 7 having the lower ends thereof provided with forks 8. In the forks S- are journaled pneumatic rubber tired wheels 9 of a type common to automobiles and bicyhe bow 2 of" the body 1, is

I body of water.

cles. The upper ends of the posts 7 are providcd'with cranks 1.0 connected by a bar 11 and connecting with said bar intermediate the ends thereof, is a steering lever 12 pivotally carried by the upper end. of the shaft 4. The wheels 9 are provided between the spokes 13 thereof, with large metallic disks l4, and these disks serve-functionally as rudders for steering the automobile when propelled through water.

Arranged longitudinally of the body 1 is an engine frame 15 supporting a conventional form ofengine 16 for imparting a rotary moven'ient to a. shaft 17, which is provided with a beveled gear wheel 18. Contiguous to the stern 3, bearings 19 are arranged for a transverse shaft or axle 20 extending-through stntiingboxes 21 carried by the sides of the body 1. The outer ends of the shafts 20 are provided with the ordinary and well known type of automobile or bicycle wheels 22. Upon the shaft 20, 1s slidably keyed a sleeve 23 adapted to rotate with said shaft. said sleeve having gear wheels '24 and 25 adapted to mesh with the gear wheel 18. In connection with the sleeve 23, a suitable mechanism can be used for shifting the same.

The stern i, of the. body 1 is provided with stulling boxes 20 for propeller shafts 27. The outer ends of the shafts 27 are provided with propellers 28. while the inner ends thereof are 'n-ovided with beveled ear a beveled ear. wheel 33 ada )ted to mesh with the beveled gear wheel 2-1.

Operation. As shown in .Fig. 3 of the drawings, the shittablc sleeve 23 is in position for power to be transmitted from the shaft. 17 to the shaft 31 through the medium of beveled gear wheels 18, 21 and 33, consequently the propellers 28 will be revolved to drive the body 1 through a stream or By shifting the sleeve 23, power can be transmitted from the shaft 17 {o 1318 shaft 20 and the body 1 driven over WVhile in the drawings forming a )art of this application there is illustrated t e preferred embodiments of my invention, I

would have it understood that the details of construction can be varied or changed as to the shape, proportion and manner of assemblage without departing from the spirit of the invention.

Having now described my invention, what I claim asnew, is

In a combined-automobile and motor boat, the combination with a driven shaft, of a body supporting said shaft and having bow and stern ends, wheels movably supporting thebow ends of said bodyfdisks arranged between the spokes of said wheels and servingfunctionally as rudders a shaft journaled transversely in said body adjacent to the stern end thereof, Wheels mounted upon the ends of said shaft, a shiftable sleeve arranged upon said shaft, beveled gear wheels carried by said sleeve and adapted to be alternately driven by the first mentioned shaft, propeller shafts journa'l'ed in the stem end of said body, propellers carried by the outer ends of said shafts, a shaft revolubly supported by said body and adapted to be driven by one of the gear wheels of said slnitaole sleeve, means for imparting a rdtary nu'ivement from said shaft tosaid propeller shafts, and means for steering the wheels at the how ends of said boat.

In testimony whereof I aflix my signature in the presence of two Witnesses.
